Transmission Cooler Upgrade

What have you guys installed for aftermarket HD transmission coolers in your 1500 Sierra, mine is a 2007 with a 4.8L regular cab 2 door and 8 foot box. To my Canadain friends has anyone used the biggest cooler Canadain Tire sells for their truck a friend recommended me one.

This is on mine, too. EAD Performance makes a mounting kit for it. The last time I checked it wasn't a part listed on their website, but contact them and ask about it, if interested, as it makes the installation a snap.

Quick update, so I bought a trans cooler at Canadian Tire the biggest they sell which is from Mr Transmission, installed it on it's own bracket in front of the rad. Happy to see the transmission running 20 degrees cooler.
